PTFE Lip Seals Shaft Sealing Ring TPD101300-T781V (130x160x12) Type D Construction Two PTFE Edges Stainless Steel Body Oil Seal
Description-PTFE seals:
Radial shaft seals with one or more PTFE sealing lip(s) are designed to withstand aggressive environments, high temperatures, high pressures and dry running that traditional radial shaft seals made of elastomeric sealing lip materials cannot withstand.
Many of the PTFE compounds are FDA approved.

Main advantages of PTFE seals include:
- High chemical resistance
- Withstand speeds up to 30 m/s (5 900 ft/min)
- Wide operating temperature range, -70 to +250 °C (-95 to +480 °F)
- Withstand pressures up to 3,5 MPa (500 psi)
- Withstand dry running
Assortment
PTFE seals without a metal case can be designed with an O-ring in the outside diameter groove to provide static sealing ability. Both the PTFE and O-ring material can be selected to meet the demands of different operating conditions, e.g. in the food industry to enable disassembly of the equipment for cleaning.
PTFE materials
The selection of seal materials typically requires a compromise between advantages and disadvantages. There are hundreds of different PTFE materials with a variety of fillers. Common fillers include glass fibre, carbon, graphite, molybdenum disulphide, metal oxides and various polymers. Each possesses different properties, appropriate for different applications and service conditions. Common to all filled PTFE materials are their improved resistance to wear and deformation.
Unfilled PTFE provides, in most cases, a lower coefficient of friction than a filled PTFE material and the lowest degree of wear of the seal counterface. However, a sealing lip made of an unfilled PTFE material has limited resistance to wear and deformation under load.
Installation
Installation procedure PTFE lips do not have the same elastic properties as rubber lips, which makes them more susceptible to damage.
Therefore, special care must be taken during installation and handling to prevent damage and help ensure proper operation and function. Shaft features such as keyways and splines, as well as drill holes, ports and sharp-edged shaft steps have the potential to damage PTFE lips. Whenever possible, these obstructions can be covered by using thin-walled installation tools made from plastic or metal. PTFE lip orientation during installation will determine the installation method.
Seals with care must be taken during handling and installation see for visualisation: Fig. PTFE seals.
Installation is more difficult when the shaft is installed against the PTFE lip (Fig. PTFE seals: a and c). This type of installation becomes even more complicated when the hardware is difficult to access or visually obstructed and may not be possible if an installation tool cannot be used. In any case, when the shaft is installed against the PTFE lip, recommends the use of an installation cone or "bullet". In lieu of installation cones, longer than normal lead-in chamfers on the shaft would be required. However, shaft features that could damage the seal (keyways, etc.) must still be covered, possibly with tape. If the shaft is installed with the PTFE lip, a smooth, burr-free radius or chamfer on the shaft end is all that is required, provided that no damaging shaft features are present as noted above (Fig. PTFE seals: b and d).
Some seals have two PTFE lips facing opposite directions. In this case, installation is always against one of the lips and an installation cone is recommended.
Other material of oil seal: Silicone, NBR, Metal & Stainless Steel, PTFE, etc.
Production equipment: includes vacuum vulcanizing machines, large-scale flat vacuum vulcanizing machines,
